JEANNETTE D. BALDWIN, OF MOOBES HILL, INDIANA.
BACK FOR PIANO-STOOLS.
QPECIEICATION forming part of Letters Patent No. 313,642, dated March 10, 1885.
(No model.)
To all whom it may concern.-
Be it known that I, JEANNETTE D. BALD- WIN, of Moores Hill, in the county of Dear:
born and State of Indiana, have invented a new and Improved Back for PianoStools, of which the following is a full, clear, and exact description.
The object of my invention is to provide a new and improved back-rest which can be s'ccured to piano-stools of all kinds without in terfering with the turning and revolving of thestool.
The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similarlet-ters of reference indicate corresponding parts in all the figures.
Figure l is a side view of a piano-stool provided with my improved back-rest. Fig. 2 is a longitudinal sectional elevation of the backrest cushion;frame. Fig. 3 is a back view of the same. Fig. 4 is a plan View of the lower end of the back-rest bar.
A curved bar or rod, A, having a circular, square, or oblong cross-section, is provided at its lower end with a fork, B, adapted to re ceive the upper end of the stem or post 0 of a piano-stool.
On the ends of the prongs of the fork screws 1) are formed,which, after the stem C has been passed into the fork B, are passed through end apertures in a cross-plate, E, whereupon nuts F are screwed on the screws D and drawn up tightly to clamp the fork on the stem of the stool. From the fork B the rod A is curved outward and upward to clear the seat G. It is then curved inward slightly, and from there it is inclined upward and outward, the 40 upper part being made straight and square or rectangular, and provided in the back with a series of notches, J. The notched part of the rod A is passed into a pocket, K, formed on the back of a wooden or metal frame, L, the front of which is upholstered and forms the back-rest proper. A binding-screw, M, is held in the pocket K; or a spring-latch can be provided in place of the binding-screw. The frame L can be adjusted higher or lower and locked in place by means of the binding-screw M, which is screwed into one of the apertures or notches J. The rod A does not interfere with revolving the seat, and the entire backrest can easily be removed from or secured on the stool.
The abovedescribed back-rest can be applied on any revolving chair, such as an ofiice-chair, 850. A spring is to be held in the cushion on the frame L, to give the desired elasticity to the backrest.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
As an improved article of manufacture, a pianestool back consisting, essentially, in the curved bar A, having a fork, B, at its lower end, said fork being screw threaded at its ends and provided with a cross-plate, E, and nuts F F, the upper rear face of the bar having notches J, and the back-rest cushion-frame having a pocket, K, and a setscrew, M, substantially as set forth.
JEANNETTE D. BALDWIN.
